application mea rbmary 2, 192s. serial No. 85,597.

The object of this invention is to provide means for mortising a door inorder to mount a lock, and to provide in the same tool means for boringthe key-hole and a hole for the knob spindle.

A further object is to provide a machine which may be operated by anunskilled Workman, and which will et'ectively and accurately do the'workof several skilled artisans, so far as the mounting of locksis-concerned.

A. still further object is to provide, in con.- nection with mountingand clamping means, a slidable element mounting an auger bit for boringholes for the mo'rtise, and a swingingly mounted elementcarrying meansfor rotating the two bits designed to bore ghe keyehole and the hole forthe knob spin- With the foregoing and other objects in View, theinvention consists in the novel construction and arrangement of elementsdescribed, illustrated and claimed, 1t being understood thatmodifications may be made within the Scope of the claim, Withoutdeparting from the spirit of the invention.

adjustable mounting. p

A main frame designated 10, may be termed a box, and is provided withlongitudinally extending guides or guideways, such as 11, in which aframe 12 is slidable longitudinally, this yframe carrying a vertically`movable crosshead such as 13, the

18 is shovvn as having been cut in frame ,ele-

ment 19 ofthe door, a door panel being illus- 'trated in cross sectionat 20. However, the

cutaway portion 18 may be assumed'to represent one of the bores made bythe auger lil. In order .tolv provide or'the vertical movement lof thevend member 13 carrying the .auger mounting means, guides 13 areprovided, and a knob or `handle 22 is connected With the verticallmovable element by means of aI threaded pin 23 passing through slot241, a Washerbeing shown at 25.

The drive for auger 14 includes a socket portion or chuck 27 rotatablewith gear wheel 28 meshing With gear Wheel 29, the latter being drivenby gear Wheel 30 to Whichv movement is imparted by hollow shaft 32.Tubular shaft 32 has a square bore, and re? ceives a square shaft 33mounting gear Wheel 311- meshing With gear Wheel 35. Wheel 35 isenmeshed with the Wheel 36, and the latter isrigid With reference toshaft 37 mounting beveled gear wheel 38, the latter being driven bylarge beveled gear Wheel 39, opierated in any suitable manner as bymeans of a crank handle Ll0. Anti-friction rollers el bear on thesurface of gear Wheel 39 and are mounted in brackets 42, as shown inFioure 2; l

t will be understood that the inner frame 12 is slidable longitudinallyof the outer frame 10, or box, incident to the advance of the auger 14into the frame member 19 of the dor, and that the telescoping elementsof the shaft including sections 32 and 33, permit this sliding movement,While continueddrive is imparted tothe au er by means of the 'gearingjust described, Between tubular shaft member 32,- and ver` tically`movable crosshead 13, 1 provide a universal joint"32" ln the lan viewof Figure 2, it Will be observed/ t at the auger is mounted in alaterally projecting portion of the frame, in order that the bit may beproperly positioned with reference to the rice' Mld edge of the door inwhich the mortise isA to be formed.

Pivotally'connected With the mainframe at the point are arms 46 and 47formed on a plate 48 provided with openings through which the chucks 49and 50 mount-- ing the transverse angers 51 and 52 extend, in the mannershown in Figure 4. These angers 51 and 52 are designed to bore the holefor the knob spindle and to bore the lgear wheels 54', 56 and 55 inposition.

' Pivoted clamping plate 48 is retained by cam levers 61, plvoted at 61toelement 61 f g the cam portions bearing on the surface of plate 48.This plate last named carries three pins 62 Which are slidable insleeves 63 carried by plate 64, and chucks 49 and 50 are adjustable insegmental slots 65 and 66 in plate 64, to permit transverse bits 51 and52 to be` correctly positioned in accordance with the space` .bet-Weenthe key-hole and knob spindlein'z"a given lock. Adjustment is maintainedby bit-mounting arms or elements 67 held by set screws 68.

Having thus described the invention, what is claimed as new is: i j y eIna boring machine, a main frame, gear* ing at one end ofwsaid frame,means for' driv-L, ing the gearing, an element slidableflongif tudinallyof the frame, a ,crosshead slid able vertically in .said element,faytool and. means on the cross head for mounting and rotating the tool,a: tubular shaft and a universal joint connecting the shaft` with saidmeans last named, and a s'haft driven by the gearing 'mounted in themain frame,

In testimony whereof aiiix my signature.

ythis shaft rotating lthe 'tubular' shaft yand p,

being s'lidable therein.
